Large quantities of pesticides are applied on crops to protect them from pests in modern agricultural practices around the globe. The two insecticides, chlorpyrifos, belonging to the organophosphorous group and endosulfan, belonging to the organochlorine group, are vastly used insecticides on agricultural crops in the last three decades. Hence, both these insecticides are ubiquitous in the environment. Once applied, these two insecticides undergo transformation in the environment either biologically or non-biologically. Microbial degradation has been considered a safe and cost-effective method for removing contaminants from the environment. Both the insecticides have been subjected to biodegradation studies using various bacteria and fungi by the researchers. Here, in this review, we report on biotransformed products formed during the course of biodegradation of these two insecticides and also discuss about the aftereffects of their transformed metabolites. This is important, because the primary biotransformed metabolites 3,5,6, trichloro-2-pyridinol of chlorpyrifos and endosulfan sulfate of endosulfan are toxic as their parent compounds and are noxious to variety of organisms. In conclusion, it is recommended to obtain microbial cultures capable of mineralizing pesticides completely without formation of any such toxic by-product before adopting bioremediation or bioaugmentation technology.
